Nobody don't know what will happen in future but i can predict that as a leader of cryptocurrency its demandand usability increasing.So hopefully in future it will be a more good  potential coin i think.

Now a days Binance and okkex are best for me.Because its Daily trading volume and and its withdrawal system are pleased me.Also its feature and many altcoin coins listing daily.I think future it will do  better service from now.

You should:
1.Learn different coins
2. Develop a comparison between coins and their features.
3. Learn technical analysis especially chart analysis
4. Follow instructions of seniors and expert.
5. Go through this group

In my portfolio I have some coins which was purchased last month here is the list
1.Ethereum
2.Ripple
3.Monero
4.waves
in these lists still now Ethereum and waves make me gainer.

One thing is crystal clear here- your loss is the gain of somebody else. That means when you lose, somebody gains. Therefore that guy is smarter than you. So, try to earn more knowledge, more experience. When you will be experienced and smart enough in trading, you will be capable to understand when to buy and when to sell.

If we consider the future prospect of bitcoin in light with it's current position, demand, technological features and long term potential, certainly long term investment in bitcoin is better.But at the same time we can not deny the short term gain generated from bitcoin.

 Bitcoin is the leader of coin market.And widely it is most popular crypto currency.Although Bitcoin is going through crisis period since its price is dropping down and down. Thing to be  optimistic here is people is still more interested to bitcoin. So we can expect 2018 to be the turning point of bitcoin. Hopefully bitcoin will reach 20k in this year.

Yea,I am afraid of hackers because before few days my 2 mew address has been hacked and I lost my all balance which was in the mew.

Here is some lists of my favorite coins which make me profit.
1.Ethereum
2.Ripple
3.Waves
4.Tio
5.Congesting

Binance and bittrex are best exchange from last 3 month and still now.

As per my view,Trading is the best way to earn better profit,but you have learn trading knowledge before starting it.

Although your investment is little bit but you can invest on a major protential coins such as
1.Bitcoin
2.Ethereum
3.Waves

I think for long term invest on potential coins such as Btc,Eth,Monero, waves will be better.if you invest on potential coins then there little risk but most probably you will be gainer.

I think it will not right decision to sell all altcoin because from few days all altcoin prices decreased so better will be wait for more profit.

Bitcoin price will again reached above $20000, I hope it's the best time to buy btc.

I am so much interested on it.surely I will apply for it.

I would like to prefer ripple rather than tron.although ripple price has increased above $3.50 but now it's price at this time under $2.so it will be increase again.
